Air-Way Pipe Fittings use NPTF(National Pipe
Thread, Fuel) dryseal threads to ensure that
a sufficient seal is achieved with the need
for sealing compounds.

SAE ORB fittings use a straight thread
along with an o-ring to create a seal
between the male thread and the female port.

SAE J514 37° Degree steel adapter fittings
use a 37° flare chamfer to provide an
excellent mechanical seal between
the male and female adapter.

NPSM fittings use a straight parallel thread
with a 30 degree cone seat to mate a male pipe
fitting with a matching chamfer.
